Magnetstek Engineering has been supplying  Neodymium Magnets for over 20 years. We manufacture strong Neodymium magnets according to our customer’s requirements and offer competitive prices. Our magnet grades ranged from N35 to N56 and N to NTH.

 NdFeB magnets are graded based on their magnetic properties and performance characteristics. The magnet grade is a standardized way to communicate the material’s maximum energy product, a crucial indicator of its strength. 

We have also pushed the industry’s maximum operation temperature to 250°C/482°F (Grade NxxTH). 
Here are the NdFeB magnet grades:

• 1. N35, N40, N42, N45, N48, N50, N52, N54, N56

These are among the lower grades, with N35 being less powerful and N52 being stronger within this range. The maximum operating temperature is 80°C/176°F while 70°C/158°F for N50 and N52.

• 2. N30M, N35M, N40M, N42M, N45M, N48M, N50M

The “M” in these grades indicates a medium temperature rating. These magnets are suitable for applications where elevated temperatures are a consideration. The maximum operating temperature is 100°C/212°F.

• 3. N30H, N33H, N35H, N38H, N40H, N42H, N45H, N48H

The “H” denotes a high-temperature rating, making these magnets more suitable for applications where heat resistance is essential. The maximum operating temperature is 120°C/248°F.

• 4. N30SH, N33SH, N35SH, N38SH, N40SH, N42SH, N45SH

The “SH” signifies a super high-temperature rating, suitable for applications with even higher operating temperatures. The maximum operating temperature is 150°C/302°F.

• 5. N28UH, N30UH, N33UH, N35UH, N38UH, N40UH, N42UH, N45UH

The “UH” indicates an ultra-high-temperature rating, making these magnets suitable for extremely high-temperature environments. The maximum operating temperature is 180°C/356°F.

• 6. N28EH, N30EH, N33EH, N35EH, N38EH, N40EH

The “EH” represents an extra high-temperature rating, suitable for applications requiring a balance of high strength and temperature resistance. The maximum operating temperature is 200°C/392°F.

• 7. N28AH, N30AH, N33AH, N35AH, N38AH

The maximum operating temperature is 230°C/446°F.
8. N30TH, N33TH, N35TH
the maximum operating temperature is 250°C/482°F.
